With a flexible modular design, the VLT® AutomationDrive EZ FC 321 is packed with standard features which can be expanded with plug-and-play options with additional features and fieldbuses. Safe Torque-Off is a standard safety feature that can be applied through hardwired safety.
Intelligent heat management removes excessive heat, promoting a longer lifespan, and the warning system gives you notice before a controlled stop in event of an error, minimising system damage.
Smart logic control can replace the needs for PLCs in some cases, with 4 parallel sequences capable of holding 20 blocks each, while the 4 menu sets allow each parameter to be individually configured four different ways to suit varying system needs.
Finally, swappable option cards enable communication over a variety of protocols should the need arise, including PROFIBUS-DP, DeviceNet, PROFINET, Ethernet/IP and Modbus TCP, with Modbus RTU coming as standard.
